The switch is in the INTERNAL position when the transmitter is shipped from the factory.
Note
External power is required for multidrop configurations.
6.1.4 Internal/external pulse power
Note
With output option code B, the pulse output can only be externally powered and there is
no PULSE switch.
The pulse loop can be powered internally by the transmitter or externally or by an external
power supply. The PULSE switch determines the source of the pulse loop power.
• When the switch is in the INTERNAL position, the pulse loop is powered internally by
the transmitter.
• When the switch is in the EXTERNAL position, a 5–28 VDC external supply is required.
For more information about pulse external power, see Connect pulse output.
The switch is in the EXTERNAL position when the transmitter is shipped from the factory.

Changing hardware switch settings
Note
The hardware switches are located on the top side of the electronics board and changing
their settings requires opening the electronics housing. If possible, carry out these
procedures away from the plant environment in order to protect the electronics.
